<p><strong>Abstract.</strong> This paper presents an investigation as to whether and how the selection of the SfM-MVS software affects the 3D reconstruction of submerged archaeological sites. Specifically, Agisoft Photoscan, VisualSFM, SURE, 3D Zephyr and Reality Capture software were used and evaluated according to their performance in 3D reconstruction using specific metrics over the reconstructed underwater scenes. It must be clarified that the scope of this study is not to evaluate specific algorithms or steps that the various software use, but to evaluate the final results and specifically the generated 3D point clouds. To address the above research issues, a dataset from the ancient shipwreck, laying at 45 meters below sea level, is used. The dataset is composed of 19 images having very small camera to object distance (1 meter), and 42 images with higher camera to object distance (3 meters) images. Using a common bundle adjustment for all 61 images, a reference point cloud resulted from the lower dataset is used to compare it with the point clouds of the higher dataset generated using the different photogrammetric packages. Following that, a comparison regarding the number of total points, cloud to cloud distances, surface roughness, surface density and a combined 3D metric was done to evaluate and see which one performed the best.</p>

Abstract Thre e-dimensional (3D) printing is an emerging technology that expanded quickly into a diverse array of clinical applications over the last decade. 3D printing, often called additive manufacturing, uses specialized printers to create objects through the addition of materials layer-by-layer. Using computer-aided design software via a 3D scanner or a digital camera, objects can be printed to highly precise and specific dimensions. This technology, including both the hardware and software, has applications in surgical procedures, dental implants and crowns, pharmaceuticals, and biomedical products. With the enormous potential of using 3D printing in multiple health care sectors, there is still limited usage for this technology in maternal and child health nursing practice. We provide an overview of 3D printing technology, review the current health care applications, and explore the opportunities and challenges of 3D printing in maternal and child nursing.

The aim of this work is to present a comparison among three software applications currently available for the Occipital Structure Sensor<sup>TM</sup>; all these software were developed for collecting 3D models of objects easily and in real-time with this structured light range camera. The SKANECT, itSeez3D and Scanner applications were thus tested: a DUPLO<sup>TM</sup> bricks construction was scanned with the three applications and the obtained models were compared to the model virtually generated with a standard CAD software, which served as reference.<br><br> The results demonstrate that all the software applications are generally characterized by the same level of geometric accuracy, which amounts to very few millimetres. However, the itSeez3D software, which requires a payment of $7 to export each model, represents surely the best solution, both from the point of view of the geometric accuracy and, mostly, at the level of the color restitution. On the other hand, Scanner, which is a free software, presents an accuracy comparable to that of itSeez3D. At the same time, though, the colors are often smoothed and not perfectly overlapped to the corresponding part of the model. Lastly, SKANECT is the software that generates the highest number of points, but it has also some issues with the rendering of the colors.

The antenna is designed as a 3D structure and is made from a conductible cylindrical antenna cone. The cone structure is realized using etching of elliptical slot array on the antenna. We use a conductible circular reflector under the proposed cone and increase the gain of the antenna. The proposed antenna provides effective bandwidth from 1GHz to 30GHz, but the gain of the proposed antenna is varying between 3dBi and 15dBi in the frequency band we are interested in. Geometrical details of the antenna are optimized numerically using parametric study using CST MWS Software Package. Once the optimal design is arrived at, the results are validated with another software package using HFSS Simulation Technology. The obtained results from both software packages agree very well.

Full textAbstract:
This study is focused on indoor navigation network extraction for navigation applications based on available 3D building data and using SFCGAL library, e.g. simple features computational geometry algorithms library. In this study, special attention is given to 3D cadastre and BIM (building information modelling) datasets, which have been used as data sources for 3D geometric indoor modelling. SFCGAL 3D functions are used for the extraction of an indoor network, which has been modelled in the form of indoor connectivity graphs based on 3D geometries of indoor features. The extraction is performed by the integration of extract transform load (ETL) software and the spatial database to support multiple data sources and provide access to SFCGAL functions. With this integrated approach, the current lack of straightforward software support for complex 3D spatial analyses is addressed. Based on the developed methodology, we perform and discuss the extraction of an indoor navigation network from 3D cadastral and BIM data. The efficiency and performance of the network analyses were evaluated using the processing and query execution times. The results show that the proposed methodology for geometry-based navigation network extraction of buildings is efficient and can be used with various types of 3D geometric indoor data.

Full textAbstract:
Traditionally, highway engineers use pencil and ruler to lay out lines and curves over contour maps for highway geometry design. Numerous calculations of stopping sight distance, minimum turning radius, and curve alignments are required during the design process to ensure safety, to minimize economic and environmental impact, and to reduce construction costs. Engineers usually perform iterative computations manually during the design process to meet design criteria and environmental constraints. The traditional process of highway geometry design is cumbersome and time consuming. The traditional approach limits engineers from taking a broader perspective in the overall highway geometry design process. Current method of three dimensional (3D) has nothing to do with highway design process. CARD/1 was developed to enhance the learning experience for highway engineers. This tool allows engineers to design the highway efficiently and to modify the design easily. A 3D highway geometry model can be generated by the software at final design to allow engineers to place themselves in the driver’s seat and maneuver through the designed highway at maximum design speed. Some key technologies of highway design with 3D-animaion based on CARD/1 was discussed in this paper.

The use of virtual laboratory classes in teaching allows the reproduction of online laboratory workshop that require expensive materials or tools, as well as making the learning process interactive and remote. The use of modern web technologies makes it possible to bypass compatibility problems on users’ computers and perform laboratory classes remotely online.The purpose of this research is to develop computer virtual 3D-laboratory class and web-access simulators for disciplines taught at the Reshetnev Siberian State University of Science and Technology (SibGU).The analysis of the current state in the field of virtual laboratory development carried out by the authors allowed us to conclude that it is impossible to use ready-made solutions. The choice of tools for the development of their own software products was made, the disciplines for the implementation of 3D-laboratory classes were selected, technical specifications were developed, methods of user interaction with objects and objects interaction with each other were developed, 3D-models needed for the visualization of laboratory work were created.The final result of the research is software products — virtual 3D-laboratory workshops for students of technical specialties, implemented with a similar set of software solutions, hosted on the SibGU server. The software products were tested by students in real classes and then the created applications were implemented in the electronic training modules of the university.The developed computer implementations of laboratory workshops are not only successfully used in the educational process of SibGU, but also allow to solve the problem of conducting laboratory classes in the forced distance form of education, as well as help to compensate for the lack of necessary equipment.Application of virtual laboratory classes helps to engage students in learning and improve their digital literacy.

3D city model is a digital representation of the Earth’s surface and it’s related objects such as building, tree, vegetation, and some manmade feature belonging to urban area. The demand of 3D city modeling is increasing rapidly for various engineering and non-engineering applications. Generally four main image based approaches were used for virtual 3D city models generation. In first approach, researchers were used Sketch based modeling, second method is Procedural grammar based modeling, third approach is Close range photogrammetry based modeling and fourth approach is mainly based on Computer Vision techniques. SketchUp, CityEngine, Photomodeler and Agisoft Photoscan are the main softwares to represent these approaches respectively. These softwares have different approaches & methods suitable for image based 3D city modeling. Literature study shows that till date, there is no complete such type of comparative study available to create complete 3D city model by using images. <br><br> This paper gives a comparative assessment of these four image based 3D modeling approaches. This comparative study is mainly based on data acquisition methods, data processing techniques and output 3D model products. For this research work, study area is the campus of civil engineering department, Indian Institute of Technology, Roorkee (India). This 3D campus acts as a prototype for city. This study also explains various governing parameters, factors and work experiences. This research work also gives a brief introduction, strengths and weakness of these four image based techniques. Some personal comment is also given as what can do or what can’t do from these softwares. <br><br> At the last, this study shows; it concluded that, each and every software has some advantages and limitations. Choice of software depends on user requirements of 3D project. For normal visualization project, SketchUp software is a good option. For 3D documentation record, Photomodeler gives good result. For Large city reconstruction; CityEngine is a good product. Agisoft Photoscan software creates much better 3D model with good texture quality and automatic processing. So this image based comparative study is useful for 3D city user community. Thus this study will provide a good roadmap for geomatics user community to create photo-realistic virtual 3D city model by using image based techniques.

Full textAbstract:
Many software packages are designed to process 3D geometric data, although very few are designed to deal with 3D thermal models of buildings over time. The software 3D Temporal Thermal Analysis (3D-TTA) has been created in order to visualize, explore and analyze these 3D thermal models. 3D-TTA is composed of three modules. In the first module, the temperature of any part of the building can be explored in a 3D visual framework. The user can also conduct separate analyses of structural elements, such as walls, ceilings and floors. The second module evaluates the thermal evolution of the building over time. A multi-temporal 3D thermal model, composed of a set of thermal models taken at different times, is handled here. The third module incorporates several assessment tools, such as the identification of representative thermal regions on structural elements and the comparison between real and simulated (i.e., obtained from energy simulation tools) thermal models. The potential scope of this software and its applications within the field of energy efficiency are presented in various case studies at the end of the paper.

Full textAbstract:
The 3D reconstruction of real-world heritage objects using either a laser scanner or 3D modelling software is typically expensive and requires a high level of expertise. Image-based 3D modelling software, on the other hand, offers a cheaper alternative, which can handle this task with relative ease. There also exists free and open source (FOSS) software, with the potential to deliver quality data for heritage documentation purposes. However, contemporary academic discourse seldom presents survey-based feature lists or a critical inspection of potential production pipelines, nor typically provides direction and guidance for non-experts who are interested in learning, developing and sharing 3D content on a restricted budget. To address the above issues, a set of FOSS were studied based on their offered features, workflow, 3D processing time and accuracy. Two datasets have been used to compare and evaluate the FOSS applications based on the point clouds they produced. The average deviation to ground truth data produced by a commercial software application (Metashape, formerly called PhotoScan) was used and measured with CloudCompare software. 3D reconstructions generated from FOSS produce promising results, with significant accuracy, and are easy to use. We believe this investigation will help non-expert users to understand the photogrammetry and select the most suitable software for producing image-based 3D models at low cost for visualisation and presentation purposes.

Full textAbstract:
With the great demand in the market for new dental software, the need has been seen to carry out a precision study for applications in digital dentistry, for which there is no comparative study, and there is a general ignorance regarding their applications. The purpose of this study was to investigate the accuracy differences between digital impressions obtained using generic G-CAD (general CAD) and D-CAD (CAD dental) software. Today, there is a difference between the design software used in dentistry and these in common use. Thus, it is necessary to make a comparison of precision software for specific and generic dental use. We hypothesized that there is no significant difference between the software for specific and general dental use. Methods: A typodont was digitized with an intraoral scanner and the models obtained were exported in STL format to four different softwares (Autodesk MeshMixer 3.5, Exocad Dental, Blender for dental, and InLAB). The STL files obtained by each software were materialized using a 3D printer. The printed models were scanned and exported in STL files, with which six pairs of groups were formed. The groups were compared using analysis software (3D Geomagic Control X) by superimposing them in the initial alignment order and using the best fit method. Results: There were no significant differences between the four analyzed software types; however, group 4, composed of the combination of D-CAD (Blender–InLAB), obtained the highest average (−0.0324 SD = 0.0456), with a higher accuracy compared to the group with the lowest average (group 5, composed of the combination of the Meshmixer and Blender models), a generic software and a specific software (0.1024 SD = 0.0819). Conclusion: Although no evidence of significant difference was found regarding the accuracy of 3D models produced by G-CAD and D-CAD, combinations of groups where specific dental design software was present showed higher accuracy (precision and trueness). The comparison of the 3D graphics obtained with the superimposition of the digital meshes of the printed models performed with the help of the analysis software using the best fit method, replicating the same five reference points for the six groups formed, evidenced a greater tolerance in the groups using D-CAD.

Remote Sensing and photogrammetric techniques have always been used in geological applications. Current advancements in the technology behind Unmanned Aerial Vehicles (UAVs), in accordance with the consecutive increase in affordability of such devices and the availability of photogrammetric software, makes their use for large or small scale land mapping more and more popular. With the UAVs being used for mapping, the problems of increased costs, time consumption and the possible accessibility problems -due to steep terrain-, are all solved at once. In this study, a custom-made UAV with 2 cameras onboard, is used to monitor two complex –regarding their topography- regions in Western Greece. One open pit limestone mine and a landslide occurring on sandy-clayous sediments. Both regions were mapped using surveying instruments like tachymeters and geodetic GPS, as well as using the aforementioned UAV system. 3D models of both regions were created using off-the-shelf photogrammetric software. For the creation of the 3D models, multiple targets were placed on the ground, to indicate GCPs with precisely known coordinates that could be identified in the high-resolution air photos, in order to maintain low Root Mean Square Error, while creating the DSMs and Orthophotos. In addition, the fish-eye effect caused by the cameras’ wide-angle lens was taken into consideration, regarding whether or not it affects the models’ overall geometric accuracy. Finally, the 3D models were compared to the survey measurements and the results are presented in this paper.

Unmanned aerial vehicles (UAVs), which have been widely used in recent years, can acquire high-resolution images with resolutions in millimeters; such images cannot be acquired with manned aircrafts. Moreover, it has become possible to obtain a surface reconstruction of a realistic 3D model using high-overlap images and 3D modeling software such as Context capture, Pix4Dmapper, Photoscan based on computer vision technology such as structure from motion and multi-view stereo. 3D modeling software has many applications. However, most of them seem to not have obtained appropriate accuracy control in accordance with the knowledge of photogrammetry and/or computer vision. Therefore, we performed flight tests in a test field using an UAV equipped with a gimbal stabilizer and consumer grade digital camera. Our UAV is a hexacopter and can fly according to the waypoints for autonomous flight and can record flight logs. We acquired images from different altitudes such as 10 m, 20 m, and 30 m. We obtained 3D reconstruction results of orthoimages, point clouds, and textured TIN models for accuracy evaluation in some cases with different image scale conditions using 3D modeling software. Moreover, the accuracy aspect was evaluated for different units of input image—course unit and flight unit. This paper describes the fundamental accuracy evaluation for 3D modeling using UAV imagery and 3D modeling software from the viewpoint of close-range photogrammetry.

In this article, we introduce a method for synchronizing operations from 2D digital mapping software to 3D digital sand table software using AI technology. This method solves the challenges and difficulties of combining 2D and 3D in military applications, such as the difference between 2D and 3D space, the accuracy and efficiency of the synchronization process, and the user experience when working with three-dimensional space. This method also uses AI models to detect and classify objects on the terrain and estimate the Z coordinates of objects on 3D sand tables. This method has been applied in the T3BD system, including 2D (GISDesktop) and 3D (GlobeDeskop) applications, and has been used by several units in the military. Experimental results show that this method achieves low synchronization times for all types of objects, from simple to complex. This method can improve the accuracy and efficiency of the synchronization process and enhance the user experience when working with three-dimensional space.

In view of the complexity of mine geology, complex mountain structure, and strong concealment characteristics, the construction of 3D visual model of mining engineering is of great significance for mine mining design, production, and residual ore remining. Based on the comprehensive analysis of the development results of the existing 3D visualization software of ore body at home and abroad and the actual needs of domestic mines, this paper determines the key technologies and solutions to be studied. Focusing on the overall goal of real ore body visualization, relying on geology, mining, computer graphics CAD technology, and computer software engineering develops a set of 3D visual modeling general components for 3D simulation software developers to realize the 3D visual operation platform of ore body with independent intellectual property rights. By introducing the Shear-Warp volume computer rendering technology into the underground 3D visualization analysis process of mining engineering, a three-layer visualization platform structure based on hierarchical model is designed from the perspective of software engineering, which effectively strengthens the low coupling of data and high cohesion of function of the system. The example analysis results show that this method can accurately simulate the 3D structure and distribution of the actual ore body and make basic preparations for reserve estimation, mining design, mining development, and prospecting prediction. At the same time, the general component of 3D visual modeling provided by the system is ready for the interface of 3D simulation involved in mining software development.

This paper gives details on the use of 3D smart printing technology to fabricate microfluidic chips for integration into biosensors for the detection and diagnosis of diseases. Additive manufacturing, also known as 3D printing, is a process used to create complex, three-dimensional objects by adding layer upon layer of material until the desired shape is formed. Microfluidic chips are used to manipulate fluids through separation and mixing. Conventional microfluidic chip fabrication methods are expensive, require much experience to operate, and are time consuming, while 3D printing offers a solution to these challenges. The 3D printing technique prints models designed using a computer-aided design software such as Autodesk Fusion 360. In this work the authors show example microfluidic chips which were printed using a 3D printer, these include an X-channel chip, Y-channel chip and a lateral flow chip which can all be integrated with biosensing setups.

This paper presents three methods of converting complex 3D models of STL type into solid models. For converting the STL models, specific approximation functions from CATIA and Creo Parametric software were used as well as 3D solid modeling methods that used sketches drawn for sections of the specific analyzed model. This conversion is required to get a solid 3D model that can be used for finite element analysis and to be processed using Boolean functions in specific CAD programs. This paper also presents a study of the effectiveness of FEA in respect to the time required for the analysis of each converted model. The analyzed STL files contain data obtained by computer tomography and are the 3D models of the human orthopedic system: the left zygomatic bone and upper part of the right femur. The presented conversion methods can be used by design engineers both in medical applications (where the complexity of forms is well known) for the design of implants and for industrial applications for reverse engineering.

Indoor space differs from outdoor environments, since it is characterized by a higher level of structural complexity, geometry, as well as topological relations. Indoor space can be considered as the most important component in a building’s conceptual modelling, on which applications such as indoor navigation, routing or analysis are performed. Therefore, the conceptual meaning of sub spaces or the activities taking place in physical building boundaries (e.g. walls), require the comprehension of the building’s indoor hierarchical structure. The scope of this paper is to perform 3D network analysis in a building’s interior and is structured as follows: In Section 1 the definition of indoor space is provided and indoor navigation requirements are analysed. Section 2 describes the processes of indoor space modeling, as well as routing applications. In Section 3, a case study is examined involving a 3D building model generated in CityEngine (exterior shell) and ArcScene (interior parts), in which the use of commercially available software tools (ArcGIS, ESRI), in terms of indoor routing and 3D network analysis, are explored. The fundamentals of performing 3D analysis with the ArcGIS Network Analyst extension were tested. Finally a geoprocessing model was presented, which was specifically designed to be used to interactively find the best route in ArcScene. The paper ends with discussion and concluding remarks on Section 4.

This work deals with the development and testing of a low latency Animation Transmission Technology (ATT) for augmented reality applications. This web-based transmission system based on AutoBahn Pyhton web server and WebSocket LibrarY (WSLAY) integrated clients has been studied to reduce packet header size and to simultaneously allow a large number of Users to interact with each other. The transmission system in the proposed system architecture allows motion sensor’s acquisition software to easily send compressed 3D quaternion-based data from transmitter to the rendering softwares at receiver side to generate real time 3D animation on an avatar. Furthermore, effects of lossy compression of quaternion data and server limitation have also been considered. Initial simulation test results with the Python server alongside WSLAY integrated clients with virtual motion sensors have been presented in this work. It has been evaluated that the network delay (ND) has a huge improvement from more than 300 ms to less than 25 ms at 100 Hz sensor sampling rate once lossy compression of 3D quaternion data is implemented. Furthermore, the effect of motion sensor sampling frequency and broadcast server limitation on maximum number of simultaneous users/sensors is also described in this work.

The classification of three-dimensional (3D) point clouds derived through the use of cost-effective and time-efficient photogrammetric technologies can provide helpful information for applications, particularly in the mapping context. This paper presents a practical study of 3D Unmanned Aerial System (UAS) – Structure-from-Motion (SfM) point cloud classification using mainly open-source software. Following a supervised classification approach that makes use of only the dimensionality of points, the entire scene was classified into three land-cover categories: ground, high vegetation, and buildings. By applying the above-mentioned approach, the level of competence in classifying a 3D point cloud of a heterogeneous scene situated in the University of KwaZulu-Natal, South Africa, was evaluated. The resulting overall classification accuracy of 81.3%, with a Kappa coefficient of 0.70, was determined by means of a confusion matrix. The results achieved indicate the potential use of open-source software and 3D UAS-SfM point cloud classification in mapping and monitoring complex environments and in other applications that might arise.
